UNITED STATES PATENT OFFICEc FRANCIS STEFFANY, OF BROOKLYN, NEW YORK.

lMPROVEMENT IN WATCH-CASES.

Sprciiication forming part of Letters Patent No. 162,321, dated April20, 1875; application filed January 11, 1875.

of Brooklyn, in the county of Kings and State of N ew York, haveinvented certain new and uset'ul Improvements in Cases for Stem-Winding\'Vatches, which are simple in construction and use, and save nearlyoue-half the gold or valuable material in the cap, and at the saine timerender the cap more attractive; and it consists in cutting out thecentral portion of the cap, and providing the same with a iian ged ringiitted therein, and a bezel, by which means either one or two picturesmay be placed-iftwo, one facing out and one in 5 or a glass may be used,if desired, all as hereinafter more fully set forth; and I do herebydeclare that the following isa full, clear and exact description ot' thesame, that will enable others skilled in the art to which ital'ipertains to make and use the same, reference being had to theaccompanying drawing, with letters oi' reference marked thereon, formingapart of this specification, in which- Figure l is a View of aWatch-case from the back, with the back and Acap partially open, showingmy improvement. Fig. 2 is au out side view ot the cap with picturesremoved, and Fig. Sis an inside view ot' the cap with the picturesinserted.

A represents the central rim, and B the back, of a watch of the usualform, and a is the cap, of the usual stemwindiiig watch to which myimprovement is applied. This cap a is attached in the usual manner, andfrom the center is cut out a large piece, of circular or oval form,around the edges of which is fitted and pressedaring, c, having aninwardlyprojecting portion and vertically-extending part, as shown inFig. 2, and spun down on the inside of the cap, as shown in Fig. 3. Onthe outside of the cap, and over the vertical part of the ring, is'litted a bezel, e, as shown in Fig. l.

y this invention a large quantity ot' valuable material is saved fromthe cap, and at the same time the cap is rendered more attractive, as alikeness or picture can be placed in the cap, looking outward or lookinginward, or two pictures may be used, if desired, and can readily be putin, taken out, or changed, by any one having the watch.

I am aware that a separate cap has been used for pictures in watches,and also that the cap ot' key-winding watches has been out out andanother pieceinserted with keyholes 3 andi do not, therefore, lay anyclaim to such devices, as they do notin any manner embody my invention,which is to save a part of the valuable material oi" the cap instem-winding watches, and at the same time make the cap more attractiveand desirable.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

In stein-winding watches, the cap a., cut out in the center asdescribed, and provided with the ring c, having an inward and upward eX-tension on the inside ot' the cap, in combination with the bezel c,whereby material is saved, and the recess formed for the insertion ofone or two pictures, all as and for the pur-
